摘要
本文对二甲苯溶剂中ＭｅＳｉＨＣｌ２ 和甲醇的反应产物Ｍｅ （ＯＭｅ）２ＳｉＨ 及ＭｅＳｉ（ＯＭｅ）３ 作了红外和核磁共振分析， 结果表明： 以红外谱图中Ｓｉ－Ｈ 和苯环吸收带作为含量分析谱带， 采用比例法， 借助工作曲线，可确定反应产物的含量。亦可以通过对各组分处于不同化学位移下质子的核磁共振分析，采用归一化法，经过换算测定反应产物混合液中各组份含量。两种测定方法均简便快捷， 并对两法的测定结果作了分析比较。
In this paper , the alcoholysis products synthesized by MeSiHCl 2 and MeOH in xylene are examined by IR and 1H NMR. The results indicated that the concentration of each composition can be calculated using the Si H bond and phenyl group absorption peak as spectrum band of quantitative analysis through the calibration curve and the scaling method in the IR analytical means , and also it can be established using the normalization method through the analysis of the different chemical shift parton H and a series of quantitative analytic calculations in 1H NMR. Both methods are simple and rapid. The results of the two methods are compared.
